|
||||
This module exploits a uninitialized variable vulnerability in the
|
||||
Annotation Objects ActiveX component. The activeX component loads into memory without
|
||||
opting into ALSR so this module exploits the vulnerability against windows Vista and
|
||||
Windows 7 targets. A large heap spray is required to fulfil the requirement that EAX
|
||||
points to part of the rop chain in a heap chunk and the calculated call will hit the
|
||||
pivot in a seperate heap chunk. This will take some time in the users browser.
